That was an ironic remark from my part.  Virtual memory management and
address spaces are not revolutionary at all: that’s how we protect
processes from stomping onto each other’s toes since the 70’s.

If the goal really is to improve OS reliability through a
multi-person-year effort, then I believe pouring that effort into a
microkernel-based design would be more fruitful.  My 2¢!
